如何编辑复合元件原理图封装库？

我有个原理图好像是因为不同orcad版本，导入时有个复合元件没pin number，现在我在各个原理图页直接修改这个元件，DRC检查时出现ERROR:  [DRC0026]  This reference has already been assigned to a different package type.改好后导入allegro时仍然出现如下问题#1 Error   [ALG0031] Pin number missing from Pin "VSS1" of Package ，求教如何将各个页的已改好子元件复合成一个元件。这个元件由8个子元件复合而成，有近千个引脚，修改起来太累人了。

终于找到了方法：If one part in a multi-packaged device is edited on the schematic, then this would cause a packaging problem. A new, unique part will be created in the design cache. Packaged parts should be edited in the library(file\open\library). If there are duplicate parts in the design cache, or similar part names with an underscore appended to the name(AND2_0)in the cache, then you should do design\replace cache to update the duplicate parts from the original library. This should get rid of the duplicate parts.
